Always good to watch a Professional at work.

I just can't get enough of these videos. Years ago I put together a small hobby foundry setup and always loved casting. Sadly these days between work and family I just dont seem to have time these days to do it anymore.

I did just enough of this in high school metal shop and jewelry classes forty years ago to be awed by the ease and speed you show ramming the molds.

I am an avid watcher and great admirer of your fantastically described and presented work - however on this occasion can I, on behalf of all your fans, give a salute to your dutiful and very helpful assistant who it seems also makes a very decent cuppa - we salute her and thank her for her contributions to our entertainment and education. Thank you again ma'am.

Being a retired US Navy Molder, it kills me when I watch someone pouring their molten metal down a sprew they can fit their hand in. Hope some of those guys listen to your advise!

Thank you again Martin. More handy tips and some cause/effect to help with future trouble shooting. Wonderfully done and much appreciated...as ever. Regards, Al

Fantastic job! That surface finish is almost mirror-like. I am about to venture into casting but I don't have a metalworking shop so your guidance will most certainly be of real help.
Thank you and cheers from Canada!

You do so many little details that a lot of other videos overlook. Keep up the good work!

Amazing finish, Martin. Thanks again. 🍺🍺👍👍

They came out great. Thanks for explaining your pouring basin, runner and gate. Can't beat a good cup of tea!. Cheers

Absolutely spotless nice and clean job there, very professional results, across YouTube I tend to find the odd one or two golden nuggets of information and you sir are definitely one of those nuggets, you have another great subscriber to add to your watching minions on how to do the job properly. Thanks for showing us this video footage and we really enjoyed and appreciated it. Regards...Phil

They look great, beautiful work as always! Take care, wishing your family a safe and merry Christmas.

I really like your analysis of your casting at end of your video. Thanks for sharing your knowelge.

[KravchenkoAudioPerth]

Thanks again Martin. I appreciated this one. Simple yes. But there are still things to learn from the seemingly simple pours.

I think that assistant did such a fine job it made the finish better...

Very interesting, as usual!! Might I point out that you talk about the temperature again, without telling us what it is! I know you think it's a straight forward thing, but the temperature is not so obvious to the in-experienced! Thanks again, it was very useful!! Regards, Matthew
